Description

Nebelscheinwerfer, insbesondere Nebelscheinwerfer bei Kraftfahrzeugen, stellen einen Zubehörartikel dar, der in den meisten Fällen nicht zur Erstausrüstung des Kraftfahrzeuges gehört. Bei der Formgebung derartig nachträglich anzubringender Scheinwerfer ist daher zu beachten, daß - das äußere Bild des Wagens nicht oder möglichst wenig gestört wird. Man ist aus diesem Grunde bereits dazu übergegangen-, I\Tebelscheinwerfer mit rechteckiger Lichtaustrittsfläche zu verwenden, da sich diese Form dem Gesicht des Wagens gut anpaßt. Störend wird hierbei empfunden, daß diese Scheinwerfer eine verhältnismäßig große Tiefe haben und daher von der Seite gesehen klobig wirken. Diese Bauhöhe ist in erster Linie bedingt durch die Länge der Glühlampe und die zwischen Glühlampe und Abdeckscheibe angeordnete Blendkappe, die den' direkten Lichtaustritt verhindert.Fog lights, in particular fog lights for motor vehicles, represent an accessory article which in most cases is not part of the original equipment of the motor vehicle. In the shaping of such a subsequent attachment Headlights should therefore be noted that - the external appearance of the car is not or is disturbed as little as possible. For this reason one has already gone over to I \ fog lights with a rectangular light-emitting surface should be used, as this shape adapts well to the face of the car. It is felt to be disturbing that these headlights have a relatively great depth and therefore from the side seen clunky. This height is primarily due to the length the incandescent lamp and the cover cap arranged between the incandescent lamp and cover panel, which prevents the direct emission of light.

Die Erfindung betrifft einen solchen Scheinwerfer und schlägt zur Verringerung der Bautiefe vor, den Kolben der Glühlampe in eine halbkugelige Ausbuchtung der Streuscheibe hineinragen zu lassen und diese Ausbuchtung als Blendkappe zu verwenden; vorzugsweise wird man sie von innen verspiegeln. Bei Verspiegelung nur der oberen Hälfte der Ausbuchtung dienen die aus der unteren Hälfte austretenden Lichtstrahlen der Beleuchtung des unmittelbaren Vorfeldes. Es ist zwar bekannt, die Glühlampe von .dem Kraftfahrzeugscheinwerfer in die Abdeckscheibe hineinragen zu lassen. Diese Ausbildung ist jedoch ausschließlich aus optischen Gründen gewählt worden.The invention relates to such a headlight and proposes to Reducing the depth in front of the bulb in a hemispherical bulge to let the lens protrude and to use this bulge as a cover cap; preferably they will be mirrored from the inside. With mirroring only the upper one The light rays emerging from the lower half serve half of the bulge the lighting of the immediate apron. Although it is known the incandescent lamp to let .dem motor vehicle headlights protrude into the cover. These However, training was chosen solely for visual reasons.

Der Scheinwerfer gemäß der Erfindung erleichtert durch seine außerordentlich flache. Form die nachträgliche Anbringung am Kraftfahrzeug in hohem Maße. Bei einer bevorzugten Ausführungsform wird man die Glühlampe so weit in die Abdeckscheibe hineinragen lassen, daß die Brennebene in gleicher oder nahezu gleicher Höhe mit der optischen Ausbildung -der Scheibe verläuft. Die erfindungsgemäße Ausbildung hat folgernde Vorteile aufzuweisen: Das Scheinwerfergehäuse kann bei voller Ausnutzung des Reflektors flach gehalten werden, da einerseits nicht mehr die volle Länge der Glühlampe unterzubringen ist, während andererseits die Blendkappe mit der kugelförmigen Ausbuchtung zusammenfällt. Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung, und zwar stellt Abb. z einen Längsschnitt durch einen Nebelscheinwerfer dar, während Abb. 2 den Querschnitt zeigt; in Abb. 3 ist ein praktisches Anwendungsbeispiel dargestellt. Der - durch den Mittelabschnitt eines rotationssymmetrischen Parabolspiegels gebildete Reflektor r trägt in seinem Scheitelpunkt die Fassung 2 für die Glühlampe 3, die mit ihrem Glaskolben q. die mit Streumitteln versehene Abdeckscheibe 5 durchdringt und in die kugelförmige Ausbuchtung 6 hineinragt. Die Brennebene 7 der Glühlampe fällt mit der die Streumittel aufweisenden Innenseite 8 zusammen. Die kugelförmige Ausbuchtung 6 weist eine Verspiegelung 9 auf, die als Mendkappe dient und bis unterhalb der Brennebene 2 reicht. Die unmittelbar austretenden Lichtstrahlen dienen zur Erleuchtung des Vorfeldes. Der Nebelscheinwerfer kann auch mit mehreren Glühlampen ausgestattet sein, wie in Abb. 3 dargestellt, wobei jeder Glühlampe eine kugelige Ausbuchtung zugeordnet ist.The headlight according to the invention facilitated by its extraordinarily area. Form the subsequent attachment to the motor vehicle to a large extent. At a In the preferred embodiment, the incandescent lamp is so far into the cover plate let protrude that the focal plane at the same or almost the same height with the optical training -the disc runs. The training according to the invention has the following advantages: The headlamp housing can, when fully utilized of the reflector are kept flat, as on the one hand no longer the full length of the Incandescent lamp is to be accommodated, while on the other hand the cover cap with the spherical Bulge collapses. The drawing illustrates an embodiment of the invention, namely Fig. z shows a longitudinal section through a fog lamp while Fig. 2 shows the cross section; in Fig. 3 is a practical application example shown. The - through the middle section of a rotationally symmetrical parabolic mirror formed reflector r carries at its apex the socket 2 for the incandescent lamp 3, which with their glass bulb q. the cover disk 5 provided with scattering agents penetrates and protrudes into the spherical bulge 6. The focal plane 7 of the incandescent lamp coincides with the inside 8 having the scattering means. The spherical one Bulge 6 has a mirror coating 9, which serves as a Mend cap and below the focal plane 2 is enough. The rays of light that emerge directly serve for enlightenment of the apron. The fog light can also be equipped with several bulbs be as shown in Fig. 3, with each bulb having a spherical bulge assigned.
